IMPROVEMENT IN WINDOW-STOP ATTACHMENTS.

Specification forming part of Letter. Patent No. 124,003, dated February27, 1872.

To all whom it may concern:

Be it known that I, CHARLES PAGE, of Mer- Connecticut, have invented anew and useful Automatic Adjustable lVindow- Stop Attachment; and I dohereby declare that the following is a full, clear, and exactdescription there of, reference being had to the accompanying drawingmaking a part of this specification and to the letters of referencemarked thereon, in which Figure l is a plan and side view of theretainingspring as it appears when first struck up and before beingbent. Fig. 2 is a side view of the spring when bent, and also the knob,which is secured to the stop and enters the spring. Fig. 3 is a sideelevation of a windowcasing and stop, illustrating the mode of securingthe latter to the casing. Fig. 4 is a horizontal section of the casingand stop at the point where the attachment is secured. Fig. 5 is a planview of a thimble, to be used, if desirable, with the spring, tofacilitate its attachment to the casing; and Fig. 6 is a vertical section of the same through the center.

My invention relates to a device to be used to attach the stop of awindow to its casing, in such manner as that the stop, when attached andin place, shall adjust itself automatically to the sash, as well in wetor damp weather as in dry, and yet permit the sash to be raised ordropped freely and easily; and my invention consists of a spring, havingits ends bent, at a point each side or each way from the middle,

in such manner that the ends approach near to each other, and these endsor arms are so formed that the edges of each arm are turned in towardthe opposite arm. The middle of the spring is perforated for theinsertion of a screw, and a hole is made in the window-casing ofsufficient size to admit the spring, which is secured to the bottom ofthe hole or recess by a screw inserted through the hole in the springand into the casin g. A conical-shaped knob, having its outer and largerend somewhat rounded, is screwed into the stop upon the side next thecasing and immediately opposite the spring, so that, when the stop isput in place and pressed in toward the casing,'the large ends of theknobs force the ends of the springs open and pass in between them, theends of the springs closing together again around the smaller part ofthe knobs, and holding said knobs firmly in their grasp and securing thestops firmly in place.

That others skilled in the art may be able to make and use my invention,I will proceed to describe the same.

In the drawing, a represents the spring, which may be of any suitableelastic metal, steel being quite suitable for the purpose; and they maybe punched from the sheet and struck into the proper form by a die, sothat the edges, near each end, shall be turned in, as at c in Fig. 1,and with the ends turned out slightly, as at i in same figure, givingthe spring a somewhat concave form near the ends. A hole, n, is made inthe middle of the spring, and the spring is bent, at a point each sideof said hole, into the form shown in Fig. 2. A knob, b, is made of asomewhat conical form, with its outer end largest and somewhat rounded,and a screw-point upon the other end; and the knob 11 and spring a areso formed and fitted to each other that when the large and rounded endof the knob is inserted between the ends of the spring said ends areforced apart; and as the knob is passed in, into the position shown inFig. 4, the ends of the spring close together again, and grasp somewhatfirmly the smaller part of the knob, holding it securely therein.

In Fig. 4, D represents the window-casing, and B represents the stop;and I adopt the following as, perhaps, the best inet-hod of securin gthe attachment to both: The sash being in place in the casing, the stopB is put in its desired place against the sash, and a hole is made witha brad-awl at 0 entirely through the stop and slightly into the casingD. The stop is then removed, and a hole or recess, 8, is made in thecasing by boring with a bit, the worm of the bit entering the puncturemade in the casing by the brad-awl. This hole or recess 8 may befive-eighths of an inch in diameter, as a convenient size, and should beof such depth as to receive entirely the whole length of the spring, asshown in Fig.4; and the spring is secured in the recess 8 in a positionwith the bent arms 0 at right angles to the length of the stop by meansof the screw r, inserted through the hole in the spring, and driven intothe casing. The knob b is then secured to the inner face of the stop Bby turning the screw-point into the hole made by the brad-awl. Thissecures the spring and the knob in place in a position exactly oppositeeach other; and when the stop is mitered at the topthere being two,three, or more of these attachments in the whole length of thewindow-the upper end of the stop may be first inserted in place, and thelower end of the stop then pressed up to the casing. The knobs will thenall enter the springs, and the stop will be held firmly in place; and ifthe sash should swell from wet or dampness, the stop will yield to thepressure of the sash against it; and when the sash shrinks again to itsoriginal size, the stop will regain its original position, following upthe shrinkage of the sash by the action of the springs upon'the knobs.If there should be any tendency of the spring to turn in securing it inplace in the recess 8, creatin g difficulty in placing the arms of thespring in a horizontal position, a thimble or cup, 71, might be used,having the webs e cast upon the outside, one opposite the other, and thespring a be riveted to the bottom of the thimble, inside, with its armsat right angles to the webs, and the thimble may then be driven into therecess 8, the webs e running parallel with and penetrating the grain ofthe wood. The outer corners of the webs could be slightly notched orrecessed to receive the head of a nail, and the whole could then besecured in place in the recess by the nails f, driven into the casingflush with its face; or two smaller webs might be made on each side,with the nail driven between them.

By the use of this spring and knob as a stopfastening, it will be seenthat the stop will always automatically adjust itself to the swellingand shrinkage of the sash, keeping both sashes always close together,and preventing the ingress of the cold and wind in winter and the dustin summer, and yet permitting the sash to be raised or dropped freelyand easily; and it it is desired to remove the sash for washing,painting, or for any other purpose, it may be easily and quickly done,even by a child, by simply drawing the stop away from the casin g at thelower end, and without any possibility of marring or injuring the casingor stop.

It may be remarked that the springs should be secured in the recesssufficiently deep that the neck or smallest part of the knob may notquite reach the point where the springs grasp the knob, by whicharrangement there will always be a tendency of the springs to draw theknob into the recess, and the stop will then always be pressed tightlyagainst the casing.

In practice, it might be found more convenient to screw the springs tothe stop, and to screw the knobs to the bottom of the recesses. Thismight be easily done by using a small endwrench to turn the knobs intothe bottom of the recesses, or by slotting the outer end of the knob andusing a common screw-driver.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

An automatic adjustable window-stop attachment, consisting of the springa and knob b, constructed and operating substantially as described.
